The Mikaelson family is possibly in the most fractured state it’s ever been in following Tuesday night’s episode of The Originals.

As chronicled in our recap, the secret is out about Rebekah and Marcel summoning Mikael, and Klaus is not happy about it. In fact, he and his sister had it out and it was pretty clear that one of them was going to die if someone didn’t intervene. Thankfully, that’s when Elijah showed up, stabbed Klaus, and told his sister to get the heck out of town. And according to Claire Holt, so much is easier said than done. “They’re on the run, and they have to decide what the future holds,” she tells EW of Marcel and Rebekah in the next few episodes. “They have to decide if they’re going to leave everything behind or if they’re going to come back and fight.”

The debate, she says, is more complicated than one may assume. “I think Rebekah knows that if they don’t leave, it may be the end of her. Klaus will find a way to put her in a box or ruin her life. She’s very scared. She also knows Marcel’s history with the city and how strongly he feels about it and how easy it won’t be for him to just go,” she says. “So it’s going to be very interesting.”

While Holt declined to spill the details of the pair’s ultimate decision, she teases, “We do have a scene in a car.”

Meanwhile, says Holt, the family will have to contend with being more fractured than ever as threats to their existence mount. And while Holt says the latest episode “won’t be the last time she sees Elijah,” the same can’t be said for Klaus. She doesn’t see Rebekah’s relationship with Klaus healing anytime soon. “I don’t think there’s a way they could ever [come back from this],” she says. “I mean, he’s done some pretty nasty things and she’s forgiven him, so maybe. But I can’t imagine, so… The next few episodes are definitely about [Klaus] dealing with the betrayal and how he feels about it and what he’s going to do.”

In EW’s Google+ Hangout with Holt on Tuesday, she opened up a bit more about filming the latest episode. Skip ahead to the 27-minute mark to hear some behind-the-scenes scoop about her wardrobe troubles during the flashbacks to 1919.
